Insights

Scoliosis is common in cystic fibrosis patients, affecting 15.6% of children and 9.8% of adults. These spinal curves are typically benign and thoracic, with specific characteristics in different age groups.

Area of Science:

  • Medical Research
  • Orthopedics
  • Pulmonology

Background:

  • Previous studies indicated a high prevalence of scoliosis in cystic fibrosis (CF) patients.
  • Two North American studies from 1978 and 1982 reported this association.

Purpose of the Study:

  • Determine scoliosis prevalence in CF patients.
  • Describe scoliosis characteristics and progression in CF.
  • Identify predictive factors for scoliosis in CF.

Main Methods:

  • Retrospective study of 316 CF patients (1982-1997).
  • Radiographic analysis of spinal deformities using Oxford Cobbmeter.
  • Correlation analysis between Cobb angle and disease-specific scores (Chrispin-Norman, Shwachman).

Main Results:

  • Scoliosis prevalence was 15.6% in 4-16 year olds (20x general population).
  • Adult CF patients (≥17 years) had 9.8% prevalence.
  • Curves were predominantly single-thoracic, apical T6-T8, with some right-sided curves in adults and nonprogressive infantile curves.

Conclusions:

  • High prevalence of scoliosis observed in cystic fibrosis patients.
  • Scoliosis in CF typically presents as benign, short, midthoracic curves.
  • Curves are apical between T6-T8 with no side predilection.

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Cushing Syndrome I: Introduction01:26

Cushing Syndrome I: Introduction

Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
